Designed to unlock the full potential of your Arduino UNO R4, the Arduino UNO SPE Shield brings professional-grade connectivity to your projects in both the maker and the industrial world. It enables high-speed data transmission and power delivery over a single twisted pair cable thanks to integrated 10BASE-T1S Single Pair Ethernet (SPE) with Power over Data Line (PoDL) capabilities, using Microchip’s LAN8651B1 component. This dramatically reduces wiring complexity and cost, while enhancing deployment speed and system flexibility.
Its built-in RS485 interface allows seamless integration with legacy systems – making it an ideal bridge between existing infrastructure and emerging technologies. Whether you’re retrofitting industrial machines, building smart energy monitoring systems, or prototyping advanced IoT devices, the SPE Shield simplifies communication between modern or legacy equipment.
Engineered for ease of use, the shield offers plug-and-play compatibility with the Arduino UNO R4 family and is supported by a dedicated open-source Arduino library, ensuring a fast and frustration-free development experience.
